Subtron - Advanced Subdomain Enumeration Toolkit

---

🔍 About

Subtron is an automated subdomain enumeration script written in Bash, built for bug hunters, penetration testers, and security researchers.

It combines multiple powerful tools:

• Amass
• Subfinder
• Assetfinder
• Httpx
• crt.sh (certificate transparency logs)

All results are deduplicated and stored neatly in results/<domain>/.
